Description

Technical Field

[0001] The utility model relates to the technical field of ventilation systems, and more specifically, to a high-efficiency ventilation and air exchange device. Background Art

[0002] Ventilation systems are systems that exchange indoor air with outside air through natural or mechanical means. Their primary purpose is to meet the respiratory needs of living organisms, remove harmful substances, smoke, and odors, while also removing heat and replenishing air. Ventilation systems are an integral part of modern buildings and play a vital role in maintaining indoor air quality.

[0003] However, current ventilation devices are usually of integrated design and usually have two sets of devices, including an exhaust system and an air supply system. The exhaust system is responsible for discharging the dirty air indoors, and the air supply system is responsible for sending fresh air from outdoors into the room. After the existing ventilation device is installed, when the outside air quality changes and the air inlet and outlet positions need to be changed, the device needs to be disassembled as a whole. For example, when ventilating a breeding house or greenhouse, when construction is being carried out outside, the air inlet will inhale a large amount of dust and impurities, affecting the air filter components inside and the indoor organisms. Replacing the air inlet position is time-consuming and labor-intensive, which increases the workload, so it needs to be improved and optimized. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, the utility model provides a high-efficiency ventilation device, including a ventilation duct 1, flanges 2 are fixedly provided on the left and right sides of the ventilation duct 1, three sets of mounting frames 6 are detachably installed inside the ventilation duct 1, and the interiors of the three sets of mounting frames 6 are respectively provided with a drying module 3, a ventilation module 4 and a filtering module 5;

[0027] A fixing hole 7 is provided on the front side of the mounting frame 6, a telescopic slot 12 is provided inside the front side wall of the ventilation duct 1, a fixing block 13 is movably installed inside the telescopic slot 12, one end of the fixing block 13 is located inside the fixing hole 7, the other end of the fixing block 13 and the telescopic slot 12 are elastically connected by a spring 14, a transmission slot 19 is provided inside the fixing block 13, a guide slot 15 is provided at the lower part of the front side wall of the ventilation duct 1, a button 16 is movably installed inside the guide slot 15, the top of the button 16 is fixedly connected to the driving rod 17, and the button 16 and the inner wall of the guide slot 15 are elastically connected by a spring 2 18.

[0028] When ventilation is needed, the staff first installs the ventilation duct 1 through the flange 2. At this time, the staff can judge the ventilation direction by observing the wind vane 9. Then the staff starts the motor 10 to drive the fan blades 11 to rotate, so that the ventilation module 4 starts to operate. The ventilation module 4 sucks the outdoor fresh air from the right side of the ventilation duct 1, and after being filtered by the filter module 5 and dried by the drying module 3, it is sent into the room from the left side of the ventilation duct 1. At this time, the right side of the ventilation duct 1 is the air inlet. When the air inlet encounters problems such as construction, the air quality is poor. The staff can hold the handle 8 with one hand and press the button 16 upward with the other hand. At this time, the button 16 pushes the drive rod 17 upward along the guide groove 15. The top inclined surface of the drive rod 17 and the transmission groove 19 abut against each other, so that the drive rod 17 passes through the transmission groove 19 and pushes the fixed block 13 into the telescopic groove 12. The fixed block 13 is further received into the telescopic groove 12, so that the fixing hole 7 loses the fixation of the fixed block 13. Then the staff The mounting frame 6 is pulled out downward. When it is pulled out, the dome-shaped feature of the top of the protrusion 22 will be squeezed by the inner wall of the limiting hole 20 and further accommodated in the limiting groove 21, so that the mounting frame 6 is completely disassembled. At this time, the staff reverses the mounting frame 6 so that the wind vane 9 points to the right, and then extends the mounting frame 6 into the interior of the ventilation duct 1. When the mounting frame 6 completely enters the interior of the ventilation duct 1, the protrusion 22 is reset by the elastic potential energy of the spring three 23, so that the protrusion 22 fixes the mounting frame 6 through the limiting hole 20. At the same time, the fixing block 13 is also reset by the elastic potential energy of the spring one 14, so that the fixing block 13 completes the fixing installation of the mounting frame 6 through the fixing hole 7. At this time, the right side of the ventilation duct 1 is the air outlet to prevent outside air from polluting the room. The staff can adjust the drying module 3, the ventilation module 4 and the filter module 5 according to needs. For example, the staff can install multiple sets of ventilation modules 4 inside the ventilation duct 1 to make the ventilation module 4 more efficient and improve flexibility.

[0029] Through the operation of the motor 10, the ventilation module 4 starts the ventilation operation, and then by pressing the button 16 upward, the driving rod 17 pushes the fixed block 13 into the telescopic slot 12 through the transmission slot 19, thereby realizing the disassembly of the mounting frame 6. Compared with the traditional device, the device ensures the ventilation quality through the setting of the drying module 3, the ventilation module 4 and the filter module 5, and the detachable design of the mounting frame 6 allows the staff to customize the installation of the three modules to meet the ventilation needs in different environments. The mounting frame 6 is simple to disassemble and quick to install, which reduces the workload of the staff and improves the ventilation efficiency.

[0030] Among them, a limiting hole 20 is opened at the rear of the mounting frame 6;

[0031] A limiting groove 21 is provided inside the rear side wall of the ventilation duct 1, and a protrusion 22 is movably installed inside the limiting groove 21. The protrusion 22 and the inside of the limiting groove 21 are elastically connected by a spring 23, and one end of the protrusion 22 abuts against the limiting hole 20.

[0032] When the installation frame 6 completely enters the ventilation duct 1 , the protrusion 22 is reset by the elastic potential energy of the spring three 23 , so that the protrusion 22 fixes the installation frame 6 through the limiting hole 20 .

[0033] Due to the dome-shaped feature of the protrusion 22, when the installation frame 6 is disassembled, the protrusion 22 will be squeezed into the limiting groove 21, so that the installation frame 6 is completely disassembled. When the installation frame 6 is installed, the protrusion 22 is reset by the elastic potential energy of the spring three 23, so that the protrusion 22 fixes the installation frame 6 through the limiting hole 20. Compared with the traditional device, the device fixes the outer wall of the installation frame 6 through the protrusion 22, preventing the installation frame 6 from falling during disassembly. At the same time, it also improves the stability of the installation frame 6 after installation, ensuring the safety of disassembly and assembly.

[0034] The ventilation module 4 includes a motor 10 fixedly mounted inside the mounting frame 6 , and an output shaft of the motor 10 is fixedly connected to the fan blades 11 .

[0035] The staff starts the motor 10 to drive the fan blades 11 to rotate, so that the ventilation module 4 starts to operate. The ventilation module 4 sucks in the outdoor fresh air from the right side of the ventilation duct 1, and after being filtered by the filter module 5 and dried by the drying module 3, it is sent into the room from the left side of the ventilation duct 1.

[0036] Among them, the bottoms of the three groups of installation frames 6 are all fixedly mounted with handles 8 , and the bottom of the installation frame 6 responsible for fixing the ventilation module 4 is provided with a wind vane 9 .

[0037] The staff can judge the ventilation direction by observing the wind vane 9.

[0038] The fixing block 13 is in the shape of a right-angled trapezoid, and the inclined end of the fixing block 13 is located inside the fixing hole 7 and abuts against the fixing hole 7 .

[0039] The fixing block 13 is reset by the elastic potential energy of the spring 14 , so that the fixing block 13 passes through the fixing hole 7 to complete the installation of the installation frame 6 .

[0040] The top of the driving rod 17 is an inclined surface, and the inner wall of the transmission groove 19 is parallel to the inclined surface at the top of the driving rod 17 .

[0041] The button 16 pushes the driving rod 17 upward along the guide groove 15 , and the top inclined surface of the driving rod 17 abuts against the transmission groove 19 , so that the driving rod 17 passes through the transmission groove 19 and pushes the fixing block 13 into the telescopic groove 12 .

[0042] The front end of the protrusion 22 is dome-shaped, and the front end of the protrusion 22 and the limiting hole 20 abut against each other.

[0043] The staff pulls out the installation frame 6 downwards. When pulling it out, the protrusion 22 is squeezed by the inner wall of the limiting hole 20 due to the dome-shaped feature on its top, and is further received into the limiting groove 21, so that the installation frame 6 is completely disassembled.

[0044] The working principle and use process of this utility model:

[0045] When ventilation is needed, the staff first installs the ventilation duct 1 through the flange 2. At this time, the staff can judge the ventilation direction by observing the wind vane 9. Then the staff starts the motor 10 to drive the fan blades 11 to rotate, so that the ventilation module 4 starts to operate. The ventilation module 4 sucks the outdoor fresh air from the right side of the ventilation duct 1, and after being filtered by the filter module 5 and dried by the drying module 3, it is sent into the room from the left side of the ventilation duct 1. At this time, the right side of the ventilation duct 1 is the air inlet. When the air inlet encounters problems such as construction, the air quality is poor. The staff can hold the handle 8 with one hand and press the button 16 upward with the other hand. At this time, the button 16 pushes the drive rod 17 upward along the guide groove 15. The top inclined surface of the drive rod 17 and the transmission groove 19 abut against each other, so that the drive rod 17 passes through the transmission groove 19 and pushes the fixed block 13 into the telescopic groove 12. The fixed block 13 is further received into the telescopic groove 12, so that the fixing hole 7 loses the fixation of the fixed block 13. Then the staff The mounting frame 6 is pulled out downward. When it is pulled out, the dome-shaped feature of the top of the protrusion 22 will be squeezed by the inner wall of the limiting hole 20 and further accommodated in the limiting groove 21, so that the mounting frame 6 is completely disassembled. At this time, the staff reverses the mounting frame 6 so that the wind vane 9 points to the right, and then extends the mounting frame 6 into the interior of the ventilation duct 1. When the mounting frame 6 completely enters the interior of the ventilation duct 1, the protrusion 22 is reset by the elastic potential energy of the spring three 23, so that the protrusion 22 fixes the mounting frame 6 through the limiting hole 20. At the same time, the fixing block 13 is also reset by the elastic potential energy of the spring one 14, so that the fixing block 13 completes the fixing installation of the mounting frame 6 through the fixing hole 7. At this time, the right side of the ventilation duct 1 is the air outlet to prevent outside air from polluting the room. The staff can adjust the drying module 3, the ventilation module 4 and the filter module 5 according to needs. For example, the staff can install multiple sets of ventilation modules 4 inside the ventilation duct 1 to make the ventilation module 4 more efficient and improve flexibility.
